Abstract
A system having RAID levels includes a storage medium, a memory and a CPU. The storage medium has at least two disks. The memory stores a striping zone information table of total disks in which a physical address of data recorded in a disk of the storage medium is converted into a logic address. The CPU modifies a striping zone information table stored in the memory in case a new disk is added to the storage medium, stores the modified striping zone information table in the memory, converts a logic address of data to be written/read out from the stored table into a physical address in response to the disk writing/reading instructions, searches positions of a corresponding disk D and a physical block B and controls writing or reading out data.
